GREENWICH — An organization that helps those dealing with cancer is hoping to attract a record crowd Sunday for its fifth annual fund-raising walk and run.

CancerCare’s Walk/Run for Hope will be held at Greenwich Point with State Rep. Fred Camillo (R-151st), a cancer survivor, reprising his role as honorary chairman.

“Being the honorary chair of this event in 2013 gave me the opportunity to learn more about what they do and just how important their mission is,” Camillo said. “A cancer diagnosis is both frightening and life-changing, but CancerCare is an organization that is dedicated to helping both those afflicted with this disease and their loved ones cope better and focus on getting better. This walk is an important part of that mission.”

The goal for the Greenwich Walk/Run for Hope is to raise $40,000 in 2017. The event has raised nearly $160,000 in the four years it has been held in town.

Funds raised during the walk will go to CancerCare’s national efforts to provide free professional support services and information to those diagnosed with cancer and their families, education workshops and financial assistance for cancer patients who are missing work because of their illness.

“This event is extremely critical for all we do,” Erica Lebensberg, CancerCare’s director of special events, said on Wednesday. “It gets us out into the community so people can find out who we are and what we offer. We provide services few others do and it’s so important for people to become aware of us. And obviously, the fundraising off this event is integral to being able offer those services.”

The family-friendly 5K event will begin with registration and check in at 7:45 a.m. The children’s half-mile fun run starts at 9 a.m.; the 5K begins at 9:15 a.m.

The minimum registration fees are $40 per adult -- someone 13 or older -- and $20 for those 12 and younger. People can also do the fun run alone for $20. All participants will receive a commemorative T-shirt. Awards will be given to the top male and female participants in the overall race and in age-based categories. The event is being held rain or shine.

“People love this event and they want to do it so they can get out there and get active, especially now,” Lebensberg said. “We’ve had such a weird winter and people are tired of being cooped up. People want to get ready for the spring and summer races they’re going to run in and people who are walking are going to use it to get in shape.”

CancerCare assists approximately 180,000 people a year through its programs and services and over the past year has provided nearly $14.2 million in financial assistance nationally.
